Abstract

An experiment of foliar application of potassium on cocoa has been carried out in Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute in Jember to study its effectiveness on the flowering and fruiting of cocoa. The experiment was arranged according to factorial design of 2 factors with environmental design of randomized complete blocks. The first factor was soil application of potassium fertilization in two levels, i.e. without fertilizer and with K-fertilizer as KCl. The second factor was application of potassium from two sources, i.e. KCl and KNO 3 , with 3 levels, i.e. without fertilizer (sprayed with water only), K-fertilizer as KCl and K-fertilizer as KNO 3. The experiment was done in 4 replicates. Parameters observed included newly formed flowers, new young fruits and the fresh-developing fruits. The results showed that foliar application of fertilizer was more effective than soil application and plant response was better in increasing new flower formation. On the other hand, the effect of soil application of fertilizer was slow. Foliar application of potassium followed by soil application of potassium fertilizer was more effective in the form of KNO 3 rather than in the form of KCl in increasing new flower formation. The dosage of foliar application of potassium could not significantly increase new young fruit formation. On the other hand, the dosage of soil application of potassium could increase new young fruit formation significantly. Key words: foliar application, kalium, flower, young fruit, cocoa.

Abstract

The Mulyo Farmer Group of Karangrejo village are the fostered villages of the University of Jember and have long been food producers, especially rice and corn, with the potential to become one of the providers of organic products according to SNI 6729:2016. Therefore it is essential to evaluate the implementation of gab against the standard requirements of organic farming systems. Some of the activities carried out are Evaluation and increasing understanding of the application of organic farming systems by continuing the practice of making biochar from agricultural waste for long-term organic fertilizer base materials; Focus Group Discussion and ongoing assistance by the Soil Biodiversity and Fertility Research Group UNEJ. The results of the activities show that the community and village officials are thrilled and open to several activities to be carried out. The results of the initial evaluation using the checklist for fulfilling the requirements of SNI 6729:2016 are based on eight variables related to fresh plants and plant products, indicating that there is no program yet to meet the needs of the organic farming system of SNI 6729:2016 or it has not yet been fulfilled. Even though it has not been fulfilled, the potential for implementing it remains open if based on its main potential, namely organic fertilizer sources and water sources (lowlands with relatively shallow groundwater tables). The existence of many livestock and agricultural waste (which is not harvested) available throughout the year can be used as a source of organic fertilizer in maintaining soil fertility or health.

Abstract

Aluminum Detoxification by Humic Substance Extracted from Compost of Organic Wastes (S Winarso, E Handayanto and A Taufiq):  Humic substance could control the activity of metal as well as exchangeable aluminum (Alexch) on acid soil. The humic substance extracted from compost of agricultural waste is rarely conducted. The objective of research was to evaluate the effect of humic substance concentration and sources to pH and Al suspension. The research had been conducted in the Soil Laboratory of Agricultural Faculty of Jember University from April to July 2009. The humic substance used in these researches was extracted from compost of rice straw (RS), soybean straw (SS), cassava starch solid waste (CSSW), and empty bunch of oil palm tree (EBOPT). The humic substance concentration treatments were 0, 10, 20, 30, 40, 50, 75, 100, 150, 200, 250, and 300 ppm. Result of the analysis showed that characteristic of humic substance was difference depending on the source material used. The humic substance extracted from SS contain total base cations (K, Na, Ca, Mg) higher (1.17%) compared with CSSW (1.07%), OPT  (0.87%), and RS (0.69%). While the humic substances extracted from RS contain total organic acid (Acetic, Fumeric, cetoglutamic, Sucsinic, Propionic, Butiric, Ocsalic, and sitric acid) higher (157 ppm) compared with EBOPT (129 ppm), SS (115%), and CSSW (108%). Among these organic acids, acetic acid was highest concentration (> 34.51% of total acid). The addition of humic substance increased pH and decreased aluminum concentration of the suspension. The higher pH increment and Al concentration reduction took placed in the suspension treated with humic substance from SS compost. The correlation between decreasing Al concentration with humic substance concentration which explained chelation was higher (r = 0.97) than decreasing Al concentration with increasing pH which explained precipitation (r = 0.93). Based on these research results, it can be concluded that humic substance extracted from agricultural waste have a good prospect as a soil ameliorant to increase soil pH, detoxify soil aluminum, and increase soil P availability on acid soil.

Abstract

As part of carbon pools, forest soil stores soil organic matter (SOM) that contains many elements including organic C, N, P, and K. These elements contribute nutrients for biogeochemical cycles within the ecosystem. This study was done to determine the ecological value of forest soil organic matter at tropical evergreen Aglaia-Streblus forest of Meru Betiri National Park (MBNP), East Java, Indonesia. The data were sampled along gradient topography in Pringtali tropical forest of TMBNP. Direct measurements of soil moisture, temperature, and pH were taken in the field. The soil samples were extracted from 6 points of soil solum using soil auger, and then oven-dried to get value of dry-weight. The elements content of organic C, N, P, and K were analyzed and estimated at the laboratory. The ecoval of SOM was appraised using developed ecological valuation tool. The result showed that SOM contributed higher ecoval of organic C (66.03 Mg ha-1) than other elements. Compared to P and K elements, N had the highest stock of element content. However, comparing to other two tropical forest ecosystems of Asia the ecoval of SOM elements in TMBNP was relatively low because of its natural geomorphological features.The ecoval of SOM elements in TMBNP was relatively low because of its natural geomorphological features. The ecovals contributed about 2.440,64 - 6.955,50 USD or 31.271.923,73 - 89.120.837,23 IDR per hectare of ecological value (d) to the ecosystem. This value was mainly contributed by organic C stock in the TMBNP forest SOM. It means the forest SOM had higher element content of organic C than N, P, and K elements. This d value is an indicator for TMBNP to protect the SOM elements meaning protecting their resources to sustain the biogeochemical cycles in the forest ecosystem. All the management and policy correlated to this protected area should consider this valuable information for their plan and actions.

Abstract

Effect of Humic Compounds and CaCO3 Combination on Aluminium and Phosphate of Typic Paleudult Kentrong Banten (S. Winarso, E. Handayanto, Syekhfani and D. Sulistyanto): Decomposition of organic matter releases humic compounds, that can chelate metals include Al in acidic soils. This chelation of Al is important for decreasing of Al activity and P fixation in acidic soils. This study was aimed to test the effect of humic compounds extracted from rice-straw compost and CaCO3 combination on aluminium activity and phosphate (available P) on an Ultisol (Typic Paleudult) collected from Kentrong Banten.  A laboratory study was conducted by series consentration of CaCO3 (0, 500, 1.000, 2.000, dan 3.000 ppm) in 8 grams of acidic soil. The acidic soil had previously been subjected to continuously addition of humic compounds and none. Then, these mix of soil and CaCO3 were added 40 ml contained 5.000 ppm humic compounds to obtain 1:5 soil:suspension ratio and  control was made by using aquadest. They were shaked for 2 hours every day and pH was measured. At 11st days incubation  Alexch (N KCl) and soluble of P (PB and PC) were measured.  The results  showed that liming or addition of CaCO3 to the acidic soils decreased Alexch (precipitated to be Al(OH)3) linearly with formula y = -0.778x + 6.108; y = Alexch (Cmol kg-1), x = CaCO3 (M); R² = 0,916. Combination addition of humic compounds and CaCO3 was able to increase pH and Alexch up to not detected. The increased of P-soluble or desorption P untill 384% took place at addition of 0.0016 M CaCO3 and 5000 ppm humic compounds. More desorption of P was observed if the acidic soils has previously been subjected to continuously addition of humic compounds, such us the increased of soluble P up to 739% at addition of CaCO3 0.0008 M.

Abstract

Humic substance (HS) extracted from composted agricultural waste contains organic acids that potential for an acid soil amandement. Functional group of COOH and OH in synthetically organic acid is higher than in HS originated from composted agricultural waste. Addition of synthetically organic acid to the HS may increase its functional group and therefore it will increase effectiveness in detoxifying aluminum (Al) and desorpting phosphorus (P) from an acid soil. Objective of reseach was to determine effect of synthetic organic acid addition to HS extracted from composted organic matter in desorpting P and detoxify Al. Research was conducted at Soil Laboratory of Agricultural Faculty of Jember University from February to May 2010. Treatment consisted of combination of four levels of HS concentration extracted from composted rice straw (0; 1,000; 2,000; and 5,000 mg kg-1) with two kind of synthetic organic acid: ethylenediaminetetraacetic acid (EDTA) and acetic acid (CH3COOH) at concentration of 5 mM. The treatment laid out in a randomized complete by design with three replications. Ultisol collected from Kentrong Banten was used in this reseach. Observation consisted of pH, Al and P concentration in the suspension at 0, 1, 2, 3, and 4 weeks after incubation. The result showed that EDTA or acetic acid treatment at concentration of 5 mM effectively increased soil pH and decreased exchangeable Al (exch-Al). However, EDTA was more reactive and having higher capability in increasing pH and detoxifying exch-Al than acetic acid. Humic substance extracted from composted rice straw at concentration of 1,000 to 5,000 mg kg-1 also effectively increased soil pH, decreased exch-Al, and increased P availability during a 4 week incubation period. The HS effect in Al detoxification and P desorption in acid soil could be boosted by addition of EDTA or acetic acid synthetic

These issues have led to declining soil quality and environmental pollution. This community engagement program aimed to enhance farmers’ capacity to convert horse manure waste into organic fertilizer as a sustainable agricultural solution. The target partners were farmer groups from three hamlets in Ngadisari Village, with a total of 15 participants involved. The methods employed included socialization of the benefits of organic fertilizer, hands-on training in production techniques (experiential learning), field demonstrations, as well as monitoring and evaluation using pre- and post-training questionnaires. The results showed marked improvements in participants’ motivation, knowledge, and skills in producing organic fertilizer, as statistically confirmed by paired t-tests (p < 0.001) and a large effect size. Correlation analysis also revealed a strong positive relationship between knowledge and skills following the training (r = 0.94). Qualitatively, participants demonstrated positive behavioral changes, readiness to adopt new technologies, and increased confidence and independence in managing organic waste. This program demonstrates that a participatory training model tailored to local needs is effective in supporting the transformation toward sustainable agricultural systems and can be replicated in other communities facing similar challenges. Keywords: agroecosystem; diffusion of innovation; experiential learning; horticultural farmers; circular economy.
